Hi,
I recently stumbled about the following issue with postfix:
DANE TLSA lookup problem: Host or domain name not found. Name service
error for name=_25._tcp.smtp-relay-in-s1.neusta.de type=TLSA: Host not
found, try again
Postfix uses knot-resolver and I found [1] as a possible similar issue
with unbound.
I would like to test if the issue persists with disabled qname
minimization, but it seems to be no configurale option.
Kind Regards
Bjoern
